My new volt makes buzzing/rattling noises in the front passenger door when the bass in my music hits certain frequencies. How do I remove it and has anyone had this issue and know what to look for? It seems if I pry at the panel near the lock pin the rattling stops, so I'm pretty sure it has something to do with the fitting of the plastic panel.

This sounds like a normal warranty problem that a visit to the dealer would rectify quickly and painlessly without cost to you. You probably could wait for the car. Why not do that???

The problem is intermittent, and I don't want to spend time on a scheduled appointment and risk them not being able to observe the issue. Whether I wait for them to do it or if I do it myself, either way I'm going to be spending time.

I have a similar problem on the driver door. Last service visit I brought it up but they said that couldn't reproduce the problem. Next visit I'm going to put some low frequency test tones on a MP3 stick and hopefully use that to show them.

Get an audio signal generator app for your phone. Then plug the phone into the AUX input of the car. Play around with frequency and volume until you hit the resonance in the door. Once done, you can easily replicate it for the tech at the dealership.

I tried this. Unfortunately, I chickened out increasing the volume 75% (my phone was already maxed). Some parts were vibrating but these were parts I never heard vibrate before. I could not reproduce the vibrating sound from the OnStar console area in the headliner. But if I go 35mph on a specific road, I can reproduce it every time, rain or shine.

I'd give it a shot, but don't expect a sweep from 0 - 22kHz will reveal 100% of all rattles.

Also, bring good hearing protection. I just used those tiny foam thingies you scrunch up then stick in your ears. I still had a headache afterwards due to prolonged sweeping (I wanted to make sure I stuck at each 5Hz for 2 seconds before progressing).

I had a sound at precisely 100Hz after Chevy took the panel off for another issue. I fist bumped all around the edges to get a tighter seal with the door clips and it went away.

I have the same problem. Around 35mph is the sweet spot. But dealer was unable to reproduce. I have to figure this one out. Does someone have the service manual how to disassemble right doors, A pillar and maybe the dash? I am really not sure. I was also thinking of using stethoscope to try to narrow down the exact spot. Do You think it could help? Is there any other method?
